The present invention relates to sharpening devices for stakes for supporting vines, plants and the like.

One of the important objects of the pres- 5 ent invention is to provide a rotatable sharpener for receiving and pointing the end of the stake together with a support for securing the stake against rotation and for alining the stake with respect to the sharpener.

A further object is to provide a support for the stake embodying adjustable means whereby stakes of various'sizes may be accommodated.

A still further object is to provide a device of this character of a simple and practical construction, which is efficient and reliable in performance, relatively inexpensive to manufacture and install in operative position and otherwise well adapted for the purposes for which the same is intended.

ther objects and advantages reside in the special construction, combination and arrangement of the various elements forming the invention as more fully hereinafter described and claimed, references being had to the accompanying drawings forming part hereof, wherein like numerals refer to like parts throughout, and in which:

Figure 1 is a top plan View,

Figure 2 is a side elevational view,

Figure 3 is an end elevational 'view,

Figure 4c is a longitudinal sectional view through the sharpener, and

Figure 5 is a front elevational view of the sharpener.

Referring now to the drawings in detailwherein for the purpose of illustration I have shown the preferred embodiment of the invention, the numeral 5 designates generally a supporting base upon the upper portion of which is a bearing bracket for a dri ye shaft indicated by the dotted lines at The sharpener 8 is secured to the end of the shaft for rotation therewith in any man ner well known in the art, the present embodiment of the invention disclosing the sharpener having its inner end provided with a recess 9 about which is formed a flange 10 for attaching to an arbor or other fixture carried by the shaft as shown at 11. The outer end of the sharpener is of a substantially conical formation ,as shown at 12 with a longitudinal recess formed in one side thereof and to the edge of which is secured the sharpenerblade 14L by cap screws 15 so that the inner edge of the blademay be extended through the opening or engaging the inner end of the stake 16 inserted in the sharpener, in a manner well known in the art.

A support 17 is provided for the stake which is of a general U-shaped construction as more clearly shown in Figure 1 of the drawings with the ends thereof turned inwardly and suitably secured to the base 5 and with its bight portion 18 extended transversely outwardly of the outer end of the sharpener.

The upper edge of the outer end 18 of the support is provided with a notch 19 having parallel perpendicular edges and within which the stake 16 is heated. The notch is of a width substantially in excess of the thickness of the stake and a pair of plates 20 are secured to the support at each side of the notch 19 by bolts 21.

The plates are formed with horizontal the rotation thereof.

By reason of the adjusting means for the stakes of various sizes may be supported therebetween so that the axis of the stake may be alined with the axis of the sharpener 8fto properly sharpen or point the end there- 0 slotted openings 22 for adjusting the plates horizontally to snugly engage the opposite side edges of the stake whereby to prevent blade mounted along one side of said opening and projecting into the hollow, a shank portion at the small end of said head, having a drive shaft receiving recess in its end and an annular bearing flange formed to project at right angles at the end of said shank portion, a driven shaft in said recess, a casing rotatably mounting said drive shaft, a U-shaped bracket forming a work support having inwardly turned flanges bolted to said casing at a point below the shaft, said bracket being so formed as to project outwardly and upwardly to a point where its bight is in alinenient with said shaft, a stake receiving notch in the bight portion of said bracket to prevent rotation of the stake, and rectangular stake adjust ing plates having longitudinal slots, adjusting bolts passing through said slots and through the bight portion, whereby said slots may be adjusted for various sizes of stakes, said stakes being guided through said notch into said sharpener in axial alineinent therewith.

In testimony whereof I aflix my signature.
